Toshiba says it has developed a 48 layer three dimensional stacked flash memory. Called BiCS, the 2bit/cell device has a capacity of 16Gbyte and is now sampling.
BiCS is said to enhance write/erase endurance and to boost write speed. Although the technology can be used in a range of applications, Toshiba expects the parts to be used primarily in solid state drives (SSD).
Toshiba is now migrating to 3D flash memory, rolling out a product portfolio addressing large capacity applications, such as SSD.
Meanwhile, Fab2 at its Yokkaichi production site for NAND flash, is scheduled to completed in the first half of 2016.
